NAME
       Type::Tiny::Manual::UsingWithTestMore - Type::Tiny for test suites

MANUAL
   Test::TypeTiny
       This is a module for testing that types you've defined accept and reject the values you
       think they should.

        should_pass($value, $type);
        should_fail($othervalue, $type);

       Easy. (But yeah, I always forget whether the type goes first or second!)

       There's also a function to test that subtype/supertype relationships are working okay.

        ok_subtype($type, @subtypes);

       Of course you can just check a type like this:

        ok( $type->check($value) );

       But the advantage of "should_pass" is that if the "EXTENDED_TESTING" environment variable
       is set to true, "should_pass" will also perform a strict check on the value, which
       involves climbing up the type's inheritance tree (its parent, its parent's parent, etc) to
       make sure the value passes all their constraints.

       If a normal check and strict check differ, this is usually a problem in the inlining code
       somewhere.

       See Test::TypeTiny for more information.

   Type::Tiny as a Replacement for Test::Deep
       Here's one of the examples from the Test::Deep documentation:

        my $name_re = re('^(Mr|Mrs|Miss) \w+ \w+$');
        cmp_deeply(
          $person,
          {
            Name       => $name_re,
            Phone      => re('^0d{6}$'),
            ChildNames => array_each($name_re)
          },
          "person ok"
        );

       It's pretty easy to rewrite this to use Types::Standard:

        my $name = StrMatch[ qr/^(Mr|Mrs|Miss) \w+ \w+$/ ];
        should_pass(
          $person,
          Dict[
            Name         => $name,
            Phone        => StrMatch[ qr/^0d{6}$/ ],
            ChildNames   => ArrayRef[$name]
          ]
        );

       There's nothing especially wrong with Test::Deep, but if you're already familiar with
       Type::Tiny's built-in types and you've maybe written your own type libraries too, it will
       save you having to switch between using two separate systems of checks.

           modules like Function::Parameters and Kavorka.
